Photo of United States Air Force tunnel boring machine at Little Skull Mountain, Nevada, USA, December 1982. There are many rumors of secret military tunnels in the United States. If the rumors are true, machines such as the one shown here are used to make the tunnels. (Source: U.S. Department of Energy.)

This is a $13 million tunnel boring machine (TBM) used for tunneling at the Nevada Test Site. (Remember that Area 51 is part of the test site.) Many other types of TBMs are used by many government agencies, including the 'nuclear powered TBM' [NTBM] that melts solid rock and leaves behind glass-like walls.

Most tunneling activity is under military installations and all information is highly restricted. Former employees of said facilities have surfaced over the years to talk of massive underground installations in places like Area 51, the Northrop facility in Antelope Valley, California (rumored to have 42 levels), and the Lockheed installation near Edwards, California.

The 'Black Budget' currently consumes $1.25 trillion per year. At least this amount is used in black programs, like those concerned with deep underground military bases. Presently, there are 129 deep underground military bases in the United States. They have been building these 129 bases day and night, unceasingly, since the early 1940's. Some of them were built even earlier than that. These bases are basically large cities underground connected by high-speed magneto-leviton trains that have speeds up to Mach 2. Several books have been written about this activity.

The average depth of these bases is over a mile, and they again are basically whole cities underground. They all are between 2.66 and 4.25 cubic miles in size. They have laser-drilling machines that can drill a tunnel seven miles long in one day. I was involved in building an addition to the deep underground military base at Dulce, which is probably the deepest base. It goes down seven levels and over 2.5 miles deep. I helped hollow out more than 13 deep underground military bases in the United States.

From Dr Bill Deagle's December 2006 Granada Forum Lecture:

I took care of John Fialla, who was best friends with Phil Schneider. How many people know about Phil Schneider? Well, they were using tunneling machines back in the mid-90s that could tunnel through a rock face at seven miles per day, that could cut through a rock face with high-energy impact lasers that could blow the nano-sized particles of rock so that there was no debris left, forming an obsidian-like core, and laying an inner core for unidirectional maglev trains that travel at Mach 2 to 2.8 underground between these very very powerful and organized cities.

There's 132 under the United States, an average of 5.36 to 7.24 cubic miles in size at an average of 1.5 to 4.5 miles underground, built, by and large, most of them in areas away from geotectonic areas - but there's going to be lots of new geotectonic faults established when you have force 11, 12, 13, 14 earthquakes hit the Earth.

This could also be of interest to you I have it down loading now. Now I would like to point out this report was made in 1988, by my estimate that was 25 years ago.
